DT’s mobile customers can also buy an unlimited data allowance for 24 hours, with those on the company’s MagentaMobil plans paying €4.95 for the add-on.

Michael Hagspihl, Head of Consumers at Telekom Deutschland, said: “The new add-on is unique on the market and gives our customers the opportunity to surf the internet and use data-intensive services without any data limits for 24 hours.”

The operator also unveiled a new Wi-Fi router, the Speedport Smart, that features up to four antennas per frequency to provide a wider range and speeds of up to 2.1GBps.

DT said up to 100 Wi-Fi devices can be added to the home network using the device.

An update scheduled for 2017 will establish the Speedport Smart as a basis for smart home applications, it added.
